Microseconds Converter
Convert microseconds to a date, and back
The 16-digit form — PostgreSQL internals, ClickHouse, Python's `time_ns() / 1000`, and Chrome's own clock, which counts from 1601 instead.
Questions people ask
The things that come up about microseconds converters, answered plainly.
Is a 17-digit number microseconds?
Probably WebKit/Chrome time, which is also microseconds but counts from 1601 rather than 1970 — so it is about 11.6 billion seconds larger. Cookie and history databases in Chromium browsers use it.
Does JavaScript support microsecond precision?
Not in `Date`, which is millisecond-only. `performance.now()` gives sub-millisecond resolution but is relative to page load, and browsers deliberately coarsen it against timing attacks.

Seconds, milliseconds, microseconds and nanoseconds, in both directions.
Milliseconds ConverterThe 13-digit form — what `Date.now()`, `System.currentTimeMillis()` and most of Java and JavaScript speak — converted both ways, with the seconds value beside it.
Nanoseconds ConverterThe 19-digit form — Go's `UnixNano`, Prometheus, InfluxDB, OpenTelemetry — with a warning about the precision JavaScript quietly loses on the way.
Unix Timestamp ConverterPaste a timestamp and get the date; paste a date and get the timestamp. The precision is detected from the digit count and shown so you can override it, and a number that is not Unix time is checked against the other eleven epochs too.
Timestamp to DateOne field, one answer — the timestamp as a date and time in your zone, in UTC, and in about thirty other encodings you might need to paste somewhere.
